Trying out Blogger's new app ( unfortunately not an iPad one).
So, at the end of the God Complex (clever title that) the Doctor takes Amy and Rory to a house on a road that looks very familiar (also whatever happened to their home in Leadworth?). Its very similar to the road seen in the Lodger, where one house had 3 stories. The third story was actually a ship in disguise - a special TARDIS-like ship that could only be piloted by Timelordy people. And at the end of this week's episode, Amy asks the Doctor to get her daughter, River, to visit sometime. And River is sort of Timelordy.
So was the ship in the Lodger River's perhaps?
Anyway, lets see if this works...
